BATTERY-TEMPERATURE CONTROLLER Specification of Letters Patent. Pate t d D 28 920 Application filed March 1?,1919. Serial in. 283,186.

To all whom it may concern:

Be it known that I, CHARLES E. LINE- YBARGER, a citizen of the United States, re

siding at 4315 Kenmore avenpe, Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Battery -Temperature Controllers, of which the following is a specification.

My invention relates to devices for regulating the temperature of storage batteries, means being provided whereby storage batteries may be kept near predetermined temperatures which are most advantageous for their efiicient action.

The invention consists of a thermostatic device, the temperature of which is controlled by the temperature of a storage battery; the device being set to operate at a predetermined temperature and being connected with a lever which actuates one or more valves, one valve controlling a suppl of heated air or gas and another, if desire controlling a supply of air at lower temperature, all so arranged as to heat or cool, by means of the gases, the storage battery.

The accompanying drawings and the following description set forth one mechanical form embodying the invention; Fi ure 1 of the drawings being an elevation o the battery with the temperature controlling devices mounted thereon; and Fig. 2 being a plan view of all of the elements which comprise my invention.

The thermostatlc device may be of any suitable form. I prefer an ordinary wafer 7 thermostat 1, which may be fastened to the The strip 7 is screwed to the side of the battery box, and is bent and out out so as to accommodate a pin 8 acting as a pivot for the lever 9. A spring 10 is fastened to the strip 7 by a screw passing through the spring into the wood of the box 2 and tends to force the end of the lever against the point The lever 9 is perforated for the passage of the pivot at the fulcrum 11. A

set screw 12 is provided for adjusting the distance between the contact point 6 and one end of the-lever 9. A set screw 13 in one end of the link 14, connects the lever 9, and the valve handles 15 and 16, through the tie-rod 17, connecting the two valve handles of the valves 18 and 19.. A pipe 20, perforated w1th holes, passes part way around the battery box 2. The pipe 20 is joined to an airhorn by means of the pipe 23, for furnlshmg air at the atmospheric temperature,

while the pipe 20 also-is connected, by means of the plpe 24, to a supply of hot air or heated gases provided in any suitable manner. The hot air is preferably provided by means of a member 25 connected with the exhaust plpe 26 of an automobile. The valves 18 and 19 control the admission of the air or gases into the pipe 20, one of the valves opening as the other closes. Preferably a box 27 incloses the battery-box 2, the pipe 20 and the thermostat and its mechanism. j

When the temperature of the battery passes a predetermined point, the thermostat 1 causes the lever 9 to move in such a direction as to close the valve 19 leading to the supply of colder air, and to open the valve 18 controlling the supply of heatedthe battery is thereby subjected to the action of the hot gases and a rise in temperature ensues. As soon as this reaches the predetermined point, the lever 9 is made, by the action of the thermostat, to move in the opposite direction, shutting off more or less of the hot gas and allowing a complementary amount of cool gas to enter through the valve 19. When a very material quantity of the exhaust gases from the-engine is used to heat the battery, it may be passed through a pipe, not perforated with rows of holes as shown, but which encircles the battery container anddischarges from the distal ends into the open air, the battery being heated mainly by. the hot pipes; and

. a perforated sleeve or concentric pipe may I a pipe for supplying heated gas, a pipe for supplying cool air at substantially the temperature of the atmosphere, a container or box inclosing the storage/battery, a valve in each of saidpipes, a tie-rod joining pivotall'y said valves in such a way that when one valve opens. the other valve closes, a lever mounted on the battery box and linked to said tie-rod, a spring holding the lever normally so as to close one of said valves and open the other, an adjusting screw at one end of. said lever, and a thermostatic device "mounted uponaside of said battery box and .coacting with one end*of said lever.

a thermostat mounted-adj acent said battery, and non-electric means operativelyconnected with said thermostat for varying the temperature of said battery.

3. The combination of a storage battery, a? thermostat mounted adjacent said battery, and means operatively connected with said thermostat for varying the temperature of said battery, said means comprising a source of gas under pressure, and means for directing said gas against said battery.

4. The combination of a storage battery, a thermostat mounted adjacent said battery,

and means operatively connectedwith said thermostat for varying the temperature of said battery; said means comprising a cas ing unted adjacent said battery, and means for passing gas into said casing, said casing having apertures therein adjacent the surface of said battery.

5. The combination of a storage battery,

a thermostat mounted on said battery, a cas-- ing mounted adjacent said battery and having apertures therein, means for-supplying gas tosaid casing, and means comprising a V 2. The combination of a storage battery,"

valve operatively, connecting said casing with said gas supplying means, and means operatively connecting said thermostat with said valve.

6. The combination of a battery, a thermostat and a casing each mounted adjacent said battery, said casing having apertures in the wall thereof, means for supplying warm gas, means for supplying relatively 0001 gas, means comprising a valve operatively connecting said casing with each of the respective'gas supplying means, and means operatively connecting said, thermostat with each of said valves.

7. The combination of a storage battery,-

a thermostaticdevice, a lever actuated by said device, a .valveopened', and closed bysaid lover, a casing partly surrounding said battery, and means for supplying gas through saidvalve-and into said casing.

8. The combination of astorage battery, a thermostatic device, a lever actuated by said device, a valve openedand closed by said lever, a casing partly surrounding said battery, and means for supplying air through said valve and into said casing, said means comprising a funnel arranged to face forwardly.
